1. What is Monitoring Well Volume?

Monitoring well volume is the total capacity of a cylindrical well, calculated using the standard formula for cylinder volume. This measurement is crucial for environmental monitoring, groundwater sampling, and well purging calculations.

2. How Does the Calculator Work?

The calculator uses the cylinder volume formula:

Where:

• \( \pi \) — Mathematical constant (~3.14159)
• \( Radius \) — Inner radius of the well (feet)
• \( Height \) — Height/depth of the water column (feet)

Explanation: The formula calculates the volume of a perfect cylinder, which is the standard shape for monitoring wells.

3. Importance of Well Volume Calculation

Details: Accurate well volume calculation is essential for determining purge volumes in groundwater sampling, calculating chemical dosing for well treatment, and assessing well storage capacity.

4. Using the Calculator

Tips: Enter the inner radius of the well (half of diameter) and the height/depth of water column. Both values must be positive numbers measured in feet.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure well radius?
A: Measure the inner diameter of the well casing and divide by 2. Standard monitoring wells typically have 2-inch or 4-inch diameters.

Q2: What if my well isn't perfectly cylindrical?
A: This calculator assumes a perfect cylinder. For non-standard well shapes, consult with a hydrogeologist for appropriate volume calculations.

Q3: How is this different from well water volume?
A: This calculates total well capacity. Water volume would require subtracting any non-water filled portions of the well.

Q4: Can I use this for horizontal wells?
A: No, this calculator is designed for vertical cylindrical wells. Horizontal wells require different calculations.

Q5: What about well screen sections?
A: For precise calculations, screen sections should be calculated separately and added to the casing volume.
